LOCKING DEVICE FOR PRINTERS GALLEYS.

Specification of Letters Patent.

Patented Feb. 24:, 1914.

Application filed June 28, 1913. Serial No. 776,367.

To all whom it may concern Be it known that I, ARTHUR E. BARTER, acitizen of the United States, residing at Ros lindale, in the county ofSuffolk and State of Massachusetts, have invented certain new anduseful. Improvements in Locking Devices for Printers Galleys, of whichthe following is a specification, reference being had to theaccompanying drawings,formingpart thereof.

This invention has reference to improvements in galley locks, so called,adapted for use in locking printing forms in printers galleys andparticularly to improvements 1n such locking devices adapted foradjustment relative to the size of the printing form whereby a printingform of any size, within limits, can be readily locked in position inthe galley.

One object of the invention is to so construct a locking device of thisnature carrying all the mechanical elements or members necessary to itsadjustment, positioning and locking in the printers galley to secure theprinting form therein.

Other objects of the invention will appear from the followingdescription.

The invention consists in the locking device herein shown and described.

Figure 1, represents a plan view of a printers galley with a printingform placed therein and secured by the improved looking device. Fig. 2,represents a sectional view of the same taken on line 22 Fig. 1 lookingin the direction indicated by the arrows. Fig. 3, represents an enlargedsectional View of the same taken on line 22 Fig. 1. Fig. 4, represents aplan view of the locking slide whereby the furniture bearing against theend of the printing form may be held in place.

Similar characters of reference designate corresponding partsthroughout.

In the art of printing it is usually desirable from time .to time totake proofs of the printing form or matter set up in the galley so thatcorrections may be made to such matter, and, to this end, it is ofcourse necessary that such printing matter, consisting of individualtype, linotype slugs or any other well known printing devices, should beso locked together that a proof can be taken.

The purpose of this invention is to provide a locking device adapted forsuch use and capable of being readily adjusted to lock in position anysize of printing form.

In the drawings it represents the usual and well known printers galleyhaving the upturned sides 6 and c and the upturned end (Z.

T, T indicate the type or printing form and f a piece of printersfurniture adapted to form a wall against the end of the print ing form.

The improved locking device comprises the straight edge member 5 havingthe right angular extension or base member 6 which latter is furnished,preferably, with a pair of longitudinally extending slots 7, 7 having,at their ends adjacent the member 5, the racks 8, 8. Secured to themember 6 are the upstanding studs 9, 9 corresponding in number to theracks 8, S, and on these studs 9, 9 are pivotally mounted the spacingarms 10, 10 which have pivots 11, 11 at their outer ends on which arepivotally mounted the complemental spacing arms 12, 12 which swingbeneath said arms 10, 10 and have ends movable beneath the base member 6which ends are furnished with the upstanding headed studs 13, 13 theshanks of which are engaged with and are proportioned to slide alongslots 7 7 between one edge of said slot and the teeth of said racks 8,8, while the shanks of said studs 13, 13 may be engaged with the teethof said racks 8, 8. The heads of said studs 18, 13 prevent thedisengagement of said studs from slots 7 7 On the pivots 11, 11 arerotatably mounted the helical cams 1 1-, 14: which have the arms 15, 15furnished with the finger or thumb plates 16, 16.

The straight edge member 5 is preferably of a length equal to that ofgalley a and said straight edge member forms a guide for the slidelocking member 17 which extends at right angles to the general extensionof said straight edge member 5 and preferably is struck up from a singlepiece of metal to form the upstanding walls 18, 18 and the bent tongue19 having the punched out projection 20 extending in line with the bottom of this slide look so that when the bent tongue 19 is slidablyengaged over the edge of member 5 said projection 20 extends partiallybeneath member 6 and prevents the upward movement of the locking member17 to disengage the tongue 19 from member 5. Pivotally mounted on thistongue 19 and operating through an opening therein is the lever 21 thepivoted end of which has a helical cam shape 22 whereby, in one positionof said lever, said cam end bears against member 5 and frictionallylockssaid tongue 19 to said member.

The types or other printing elements T, T are first arranged in thegalley and the straight edge member 5 of the improved galley lock isplaced against one edge of said combined types or printing elements,spacing armsl2, 12 are then moved toward arms 10, 10 until cams 14: 14are approxi mately in contact with a wall of the galley, said cams 14,14 are then swung on their pivots and act against the galley wall withwhich they are in contact to crowd member 5 of the galley lock againstthe type. The strip of iurniture f is now placed against the end of thetype matter and the slide locking member 17 is slid along on thestraight edge 5 until one of the walls 18 of sand member 17 bearsagainst said furniture f when lever 21 is swung to locking position. Aproof of the type matter, thus locked, may now be taken after which thegalleylock may be released, as to its pressure on the type, by thereverse swinging of the cams 14, 1a and any desired corrections may bemade or the galley lock may then be removed from the galley.

Having thus described my invention I claim as new and. desire to secureby Let ters Patent.

1. A galley lock of the nature described 7 comprising a straight edgemember having spacing members, helical locking cams pivotally mounted onsaid spacing members, and an endlocking member slidably mounted on saidstraight edge member and having a locking means.

2. A galley lock of the nature described comprising a straight edgemember having a laterally extending base member, a pair of spacing armsof which one arm is pivotally connected with said base member,

Copies of this patent may be obtained for and locking cams pivotallymounted at the junction 01 said spacing arms.

3. A galley lock of the nature described comprising a strai ht edgemember having .a base furnished wlth a rack, a spacing arm plvotall'ymounted on said base, a second spacing arm pivotally connected with saidfirst arm and having at its free end means for engaging said rack, and ahelical cam rotatably mounted on the pivot connecting said arms.

4. A galley lock of the nature described comprising a straight edgemember having a lateral base member furnished with a longitudinal slothaving a rack, a spacing arm pivotally mounted on said base member, asecond spacing arm pivotally connected with said first arm and having atits free end a stud slidable in the slot of said base member and adaptedto engage said rack, and a helical cam rotatable on the pivot connectingsaid arms.

5. A galley lock of the nature described comprising a straight edgemember having a lateral base member furnished with longitudinallyextending slots having racks, arms pivotally mounted at the upper sidesof said base member, spacing arms pivotally connected with said firstmentioned arms and having their free ends extending beneath said basemember and provided with studs slidable in the slots of said base1nember and adapted to be engaged with the racks thereof, helical camsrotatable on the pivots at the junctures of said pairs of arms, saidcams having thumb pieces, and an end locking member slidable on saidstraight edge member and having a tongue engaged beneath said basemember, and a locking lever pivotally mounted on said slidable memberand adapted to frictionally engage said straight edge member.
